Question about 2000 Honda Passport
I have a 2000 honda passport that the cel is on. i pulled the codes and they are po171 po172 po174 po175. i have checked for vacum leaks (none) replaced maf (auto zone) not sure if it isn't a defect. next is to check the fuel pressure but not sure what is a exceptable psi range?
If the fuel pressure was low enough to give lean codes then u would have a loss of power that you would easily notice, you say you checked for vacuum leaks, did you use a can of carb spray or a bottle of propane? it only takes a very small leak to trigger the codes, spray carb spray around the intake area, see if the engine sound changes, this will indicate a leak,
